Greenland Ice Sheet's 2017 weigh-in suggests a small increase in ice mass
For nearly two decades, Greenland has been losing mass every year.
An exceptionally good snow year and a short surface melting season may result in a small ice gain in 2017.
The estimated increase of ~44 billion tons will do little to change the ice sheet's trajectory, however. Even if the ice sheet saw similar gains each year, it would take more than 80 years for it to return to its 2002 mass.
